Maybe I'll give the Anniversary Update another go again, who knows, it might decide to work on my machine.

Re. the monitor, first thing I usually think of when anyone mentions a TV, monitor, computer, or such needs to "warm up" before it works properly is the electrolytic capacitors in the switchmode PSU, (or main board), have started getting way out of spec due to age.

Can be replaced easily enough if you're competent with a soldering iron but there are some lethal voltages lurking in the PSU, especially the discharge from the main capacitor.

Salvaged plenty of things just by replacing the capacitors in the equipment, spending <$20 and an hour or so has always been preferable to spending a lot more to replace the equipment, eg. salvaging a discarded complete Dell XPS730 by replacing 5 capacitors on the motherboard

Failing to come out of sleep has been happening to me, ever since anniversary too, may be even before anniversary actually. I blamed it on it being an Windows 7 era Vaio not officially Windows 10 supported. Have been doing same thing as no sleep, only shutdown or on.

Not to hijack, but if anybody reading this has any advice for my version would be appreciated.

Wasn't this high voltage thing a thing from the past? CRT monitors/TVs needed 10.000Volts to get the system started, but I thought that such high voltages aren't required for LCD-/LED-based monitors or TVs.

But as of about mid-December, my other monitor has started having issues when I turn on my PC, though I'm fairly confident it's unrelated. My screen is a pale grey, then looks like "clouds" form on it, then there are either some bright or dark lines of pixels that show up at the top, soon replaced by several lines of glitchy pixels at the top of the screen which gradually expand down toward the bottom until finally the picture comes back, but the colors are messed up. Once it reaches that point, I can shut the monitor off and turn it on again and the colors are all good. But if I try to restart the monitor earlier in the process, it continues about from where it left off. It's like it needs to "warm up" a bit first. It has happened both when resuming from sleep and also when powering on from an off state.

I took a video of it using my tablet. It seems to be worse and last longer since I took this video:
